Actually, it is not the VHF/UHF ("encoder") mics that are generally the issue. The real problem is with the HF "desk" mics (MC-55, MC-60A, MC-80, & MC-85) that use pin 5 to power a preamplifier or bias the electret capsule. MC-55, 80 and 85 use electret capsules and require power on "pin 5" or the use of batteries. The MC-60A is a dynamic mic that will work with the K2/K3 as long as the preamplifier is bypassed (preamp switch "off"). The MC-90 - a dynamic desk mic with no preamp - works without modification. 73, ...
